The label changes include modifications to the Warnings, Precautions and Adverse Reactions sections of Heparin Sodium in 5% Dextrose Injection and Heparin Sodium in 0.9 % Sodium Chloride Injection.

The labeling changes in part were spurred by the much-publicized overdosing of actor Dennis Quaid’s newborn twins, who nearly died in 2007 when they were accidentally given 1,000 times the intended dose of the blood thinner. The Quaid’s case is just one of many cases where health care workers claimed to have confused high-dose and low-dose heparin. Some argue that the two bottles can be easily confused.

Heparin is generally used when a patient – adult or infant – receives fluids through a central line to prevent a blood clot from forming, which could eventually grow and break off and kill a patient. But if the blood is too thin, it puts the patient at risk for life-threatening bleeding or hemorrhages, including in the brain.

Heparin has seen its fair share of the spotlight lately. Last year more than 80 Americans died and hundreds more were sickened after receiving doses of heparin made at Baxter International’s China plant. An investigation found that lots made in that plant were contaminated with oversulfated chondroitin sulfate (OSCS). The contaminant can cause serious allergic reactions and even death.

Even on the campaign trail, Obama’s camp said it would support the plan but that there would have to be measures in place to ensure the FDA was properly inspecting the plants where drugs are being manufactured.

After all, it was just one year ago that hundreds of people became ill and more than 80 died after receiving injections of the blood thinner heparin that was later found to have been contaminated at pharmaceutical giant Baxter International’s manufacturing plant in China.

The FDA later admitted that it simply didn’t have the manpower to inspect all foreign food and drug manufacturing plants and thus couldn’t ensure the safety of those products. Late last year, the agency began placing food and drug inspectors to oversee the safety of foods and drugs imported into the U.S. The first three offices were opened in China.

Allowing Americans to purchase their drugs from foreign countries can provide a tremendous savings to consumers, but some lawmakers say that it is too risky a gamble. At a hearing of the Senate Finance Committee, Kansas Republican Pat Roberts asked the White House if it was in favor of first establishing some controls before moving forward with the importation plans. “Would you also agree that, if such a proposal were to move forward, we should demand that any drug imported into the U.S. meet the same high safety and efficacy standards of our FDA including bioequivalency standards?” he asked.

White House budget director Peter Orszag answered by simply saying, “Yes.”

Heparin is routinely used before certain types of surgery or other procedures are preformed to prevent clotting. Afterward, doctors will often remove the blood thinner to avoid unwanted bleeding by using the medication protamine.

Protamine is a weak anticoagulant drug that is administered intravenously and acts as a heparin antagonist. But protamine carries a risk of serious side effects such as difficulty breathing; swelling of the mouth, face, lips or tongue; wheezing; muscle pain; confusion; fainting; fast or irregular heartbeat; mood changes; seizures; slurred speech; headache; loss of consciousness; unusual hunger; unusual sweating; and weakness.

Many people also experience allergic reactions from heparin, including organ failure, heart problems and shock. Batches of the drug also have been recalled or seized by the federal government after more than 80 people died and hundreds more were sickened by heparin that was found to have been contaminated during manufacturing.

In an effort to find a safer product to remove heparin from the bloodstream, Krzysztof Szczubialka and his team of researchers have developed a new product made of microscopic polymer beads from modified chitosan, a product of shellfish. Lab tests show that the new material reduced heparin concentrations to nearly zero within 10 minutes. The product will be detailed in the December issue of American Chemical Society’s monthly journal, Biomacromolecules.
